ABSTRACT:
FIELD OF INVENTION
The present invention relates to a portable rectangular tabletop picnic cooler that enables picnic food to remain cold for an extended period of time while on ice.
DESCRIPTION OF PRIOR ART
The use of portable picnic coolers is known in prior art. More specifically, portable coolers heretofore devised and utilized for the purpose of storing food and beverage items and keeping them cold. Prior art also illustrates an abundance of food serving apparatus, which require refrigeration units or mechanical means thereof. Prior art also illustrates tabletop salad bars and coolers that are known to consist basically of familiar, expected and obvious structural configurations, not withstanding the myriad of designs encompassed by the crowded prior art, which have been developed for the fulfillment of countless objectives and requirements. In addition, the prior art fails to describe a portable rectangular tabletop picnic cooler that is comprised of a dome less transparent lid that does not need to be assembled or disassembled.
U.S. Pat. No. 4,662,188 issued to Hullihan on May 5, 1987, U.S. Pat. No. 5,257,509 issued to Harris on Nov. 2, 1993, U.S. Pat. No. 3,347,346 issued to J. R. Young on Oct. 17, 1967, and U.S. Pat. No. 4,106,597 issued to Shook et Al on Aug. 15, 1978 illustrates portable food containers having a rectangular base and lid enclosure. However, none of the above containers have a rectangular transparent lid or a drain hole that is located through the base.
U.S. Pat. No. 5,727.857 issued to Smith on Mar. 17, 1998 and U.S. Pat. No. 4,852,741 issued to Van Benschoten on Aug. 1, 1989 illustrate portable knockdown food containers. However the containers have to be assembled and disassembled before and after use. Both containers have domed shaped transparent lids but neither lid is hingely attached to a base.
U.S. Pat. No. 767,321 issued to F. W. Wheldon on Aug. 9, 1904 illustrates a rectangular refrigerator that uses ice as the cooling agent and has a drain hole located through the base. However the refrigerator does not have a rectangular transparent hinged lid and it is not equipped with a carrying handle
U.S. Pat. No. 271,241 issued to J. Hobbs on Jan. 30, 1883 illustrates an apparatus for treating artificial butter while being placed on ice. However the apparatus does not have a transparent hinged lid or a carrying handle.

Coughlin on Nov. 1, 1927 illustrate storage containers tat have the means to display cooled food items. However they are too expensive to build, too large and are not portable.

No. 4,375,758 issued to Simmons on Mar. 8, 1983 illustrated are a portable ice table and a self serve type salad bar both of which use ice as the cooling agent. However neither have a rectangular transparent lid that protects the cold food items from ambient air temperatures.
U.S. Pat. No. 3,130,288 issued to F. F. Monaco Et Al on Apr. 21, 1964, U.S. Pat. No. 3,710,589 issued to Brown et Al on Jan. 16, 1973 and U.S. Pat. No. 3,241,706 issued to F. F. Monaco Et Al on Mar. 22, 1966 illustrate a plurality of food service containers and refrigerated devices that use ice as the cooling agent. Many of which have dome like lids that aid in maintaining the freshness of the foot items placed inside the container. However none of these patents have been constructed with a drain hole that is located on the bottom of the base. Unlike my present invention, none of these patents have been constructed so that the base is elevated to allow melted ice water to be directed from the back of said base to the front, where the drain hole is located.
U.S. Pat. No. 108,989 issued to J. Elison on Nov. 8, 1870, U.S. Pat. No. 3,025,947 issued to A. D. Hammer on Mar. 20, 1962, and U.S. Pat. No. 4,336,883 issued to Krug et Al on Jun. 29, 1982 illustrates a lunch box3, a portable lunch box and an insulated container respectively. All of which are designed to keep food items fresh within an enclosure. However none of these inventions have a transparent hinged lid or a drain hole.

Petty on Oct. 21, 1952 illustrated are rectangular briefcase type containers some of which may contain a lid, a carrying handle and or both. However none of them have a transparent hinged lid or have been constructed so that the base is elevated to allow melted ice water to be directed from the back of said base to the front, where the drain hole is located.
U.S. Pat. No. 3,020,113 issued to V. D. Molitor on Feb. 6, 1962 and U.S. Pat. No. 3,424,510 issued to H. J. Moon on Jan. 28, 1969 illustrates food display carts with transparent dome type lids. However these carts are designed with four legs that extend down and have wheels attached to the bottom of each leg, which allows the cart to be pushed along the floor. These carts do not have a drain hole and are not intended for tabletop use.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new rectangular tabletop picnic cooler which is comprised of a dome less transparent lid that is hingedly secured to a base, where said base is constructed so that the base is elevated to allow melted ice water to be directed from the back of said base to the front, where the drain hole is located.
SUMMARY OF THE INVENTION
The present invention is a portable rectangular tabletop picnic cooler in the configuration of a briefcase or attache case, or similar there of. The ideal material used to construct the cooler preferably is a lightweight and durable injection molded thermoplastic or other plastic means. The cooler enables cold food items to remain cold for an extended period of time using ice as the cooling agent. The cooler is uniquely designed with a rectangular transparent hinged lid that allows the individual user to view the food items that are placed into the cooler. For example, if the individual user does not want any of the items placed in said cooler then the lid remains in the closed position. This allows the food inside the cooler to remain cold by not exposing the contents of said cooler to ambient air temperatures, every time the lid is open. The cooler can be used indoors and outdoors. When used outdoors a flexible drain hose may be pushed onto the bottom of the drain hole to direct the melted ice water away from the picnic area. If used indoors the drain hole plug can remain in place or a flexible drain hose may be directed into a bucket.
One object of my invention is to provide a cooler that can be inexpensively made and durable and widely available to the public. A lightweight cooler that can be manufactured in a variety of eye appealing colors. Another objective is to provide a cooler that can be easily carried and easily stored. Yet another object of my invention is to a provide a cooler that does not need to be assembled or disassembled before or after use. It is also widely known that sometimes whether it be at a picnic, party or social gathering not everyone arrives at the same time, this cooler fulfills another objective by allowing cold food items to remain cold for an extended period of time while on ice. Another objective of my invention is to provide a cooler that can receive a multitude of different serving dishes such as plates, pots, Tupperware, and the like. Ideally the cooler is meant to be used with inexpensive aluminum tins. Using aluminum tins may minimize cleanup time and may cut down on household water use. For example, after a picnic is over and items need to be
